UNITED STATES PATENT OFFICE.

STRETGHER, SLEEPING- OR SICK FRAME.

Application filed May 31, 1927, Serial No. 195,513, and in the Netherlands May 16, 1924.

The present invention relates to a stretcher sleepingor sick frame having side members or beams and transverse membe'rsor beams and a supporting surface or berth, which may be stretched by adjusting the said members or beams.

A stretcher of this type is known in which. the berth is secured to the transverse beams,

while the side beams consist of two telescop ing portions. The berth may be stretched said portions the one out of the other. In another known construction the stretcher comprises tubular supporting are rigidly secured to telescoping short beams. The berth in this construction consists of canvas or other suitable material preferably detachably connected to the frame, e. g. by means of rings or the like.

According to the present invention the berth is attached to the side beams only, which at their ends embrace the transverse beams in such a manner that the embracing pieces are slidable along the transverse eams and adapted to be fixed thereto,eventually by means of hooks or pins, which may be inserted in holes of the transverse beams.

This simple construction has the advan tage that it is cheap and efficient. the fact that the berth is secured to the side beams only, the berth remains always straight in longitudinal direction which is important in particular when transporting persons having abdominal wounds and the like.

stood with reference to the accompanying drawings illustrating it .by way of example.

Fig. 1 is a front elevation of a stretcher according to the invention.

Fig. 2 is a partial plan view of the stretcher.

Fig. 3 is a cross section and Fig. 4 shows a lever-system for stretching the berth.

The frame consists of two. strong bars at the short sides, the so called transverse beams 1 of the frame, and of two firm tubes at the long sides, the so called side beams 2, which tubes are provided at both ends with a flattened portion 3, having a Owing to The invention will be more fully underhole for the passage of the transverse beams, so that the two side beams are adapted to be slid over the transverse beams, while they may be locked in various means of pins or hooks 4:, which may be in serted in holes 50f the transverse beams.

The berth 6 may be connected to the side beams in any convenient manner. Now if the tubes, after the berth has been attached thereto, are slid upon the beams at the head and foot end (first the one tube and then the other) the berth may be stretched by moving the side beams away from each other as much as possible. This is accomplished e. g. b means of a lever-system shown in Fig. 4. his lever system consists of a pair of levers cooperatin in the manner of a pair of shears. T ese levers are pressed away from each other and thereupon are fixed to the transverse beams by means of the set pins or hooks 4. If by expansion of the cloth or canvas of the berth the tension is somewhat reduced, it is quite easy to readjust the side beams in a position corresponding to the next holes 5 of the transverse beams. The said beams may beprovided with supports 7 in order to make the frame also suitable for use as a camp-bed or the like. I claim: A stretcher comprising side beams, transverse beams at the respective ends of the side beams and provided with a series of openings at the end portions, a berth adapted to be stretched between the side beams, the berth being attached only to the side beams, the ends of the side beams embracing the transverse beams in such a manner that the embracing portions are slidable along and relatively to the transverse beams, and means for fixing the beams in the desiredposition of adjustment including pins engageable with the openings in the end portions of the transverse beams on one side of the side beams and having hook-like terminals on the upper ends for embracing the upper edges and the opposite sides of the said side beams to prevent movement of the side beams in either direction on the transverse beams.
